This paper presents non-destructive evaluation of microstructures of heat treated steels by the Magnetic Barkhausen Noise (MBN) method. Various steel specimens having different microstructures were produced by appropriate heat treatments. All specimens were characterized by metallographic examinations, hardness and MBN measurements. The results showed that MBN parameters are highly sensitive to the variations in the microstructure, and this method is a promising candidate for practical non-destructive characterization of heat treated steels.

Microstructural characterization of hypoeutectoid steels quenched from the Ae1 - Ae3 intercritical temperature range by magnetic barkhausen noise technique Boyacıoğlu, Beril; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2006) This thesis aims to examine the possibility of using Magnetic Barkhausen Noise technique in characterizing the ferritic-martensitic microstructure of hypoeutectoid steels quenched from the intercritical temperature range. For this purpose, rectangular specimens were prepared from SAE 1020, 1040 and 1060 steels. The specimens were heated at different temperatures within the intercritical temperature range and then quenched into water. Microstructures of the specimens were characterized by metallographic exam...
Non-destructive determination of residual stress state in steel weldments by Magnetic Barkhausen Noise technique Yelbay, Hasan İlker; Çam, İbrahim; Gür, Cemil Hakan (2010-01-01) The purpose of this study is non-destructive determination of residual stresses in the welded steel plates by Magnetic Barkhausen Noise (MBN) technique. A MBN-stress calibration set-up and a residual stress measurement system with scanning ability were developed. To control the accuracy and the effectiveness of the developed system and procedure, various MBN measurements were carried out. The MBN results were verified by the hole-drilling method. Microstructural investigation and hardness measurements were ...
Microstructure and nanomechanical behavior of sputtered CuNb thin films Abboud, Mohammad; Motallebzadeh, Amir; Duygulu, Özgür; Maaß, Robert; Özerinç, Sezer (2021-09-01) We report on the mechanical properties of Cu–Nb alloys produced by combinatorial magnetron sputtering. Depending on the composition, the microstructure is either fully amorphous (~30–65 at.% Cu), a dispersion of Cu crystallites in an amorphous matrix (~70 at.%), or a dominant crystalline phase with separated nanoscale amorphous zones (~80 at.% Cu). Nanomechanical probing of the different microstructures reveals that the hardness of the fully amorphous alloy is much higher than a rule of mixture would predic...
Microstructural Investigation and Phase Relationships of Fe-Al-Hf Alloys Yildirim, Mehmet; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (Springer Science and Business Media LLC, 2014-4-2) The effect of Hf addition on microstructures, phase relationships, microhardness, and magnetic properties of Fe50Al50-n Hf (n) alloys for n = 1, 3, 5, 7, and 9 at. pct has been investigated. At all investigated compositions, the ternary intermetallic HfFe6Al6 tau (1) phase forms due to the limited solid solubility of Hf in FeAl phase and tends to develop a eutectic phase mixture with the Fe-Al-based phase. The Hf concentration of the eutectic composition is found to be 7 at. pct from the microstructural exa...
Vector Magnetic Characteristic Analysis of Induction Motor considering Effect of Harmonic Component due to Secondary Slot Enokizono, Masato; Kunihiro, Naoki (2011-09-10) This paper presents load characteristics of a three-phase induction motor model core calculated with the finite element method considering two-dimensional vector magnetic properties. Influence of harmonic components due to the secondary slot of the rotor core on the total iron loss is investigated. In this paper we propose a new iron loss calculation method to consider higher harmonic components.
